The equation of a circle in standard form is
where (h, k) is the center of the circle, and r is the radius if the circle.
We need to find the radius and center of the circle.
We are given a diameter, so to find the center, we need the midpoint of the diameter.
M = ((-6 + 6)/2, (6 + (-2))/2) = (0, 2)
The center is (0, 2).
To find the radius, we find the length of the given diameter and divided by 2.

Answer:
58 square feet
Step-by-step explanation:
The room is already broken down into two smaller rectangles.
The smaller of the two measures 4 ft by 2 ft. , so substitute 4 for
and 2 for
.
(smaller rectangle)
, or
.
(smaller rectangle)
The larger measures 10 ft by 5 ft, so using the same method, multiply times
.
(larger rectangle)
, or
.
(larger rectangle)
Add the two rectangles' areas together to find the total area of the room.
8 + 50 = 58
